HENRY H. WARNER, OF TACOMA, WASHINGTON. ASSIGNOR TO SAFETY INVESTMENTCOMPANY, OF TACOMA, WASHINGTON. A CORPORATION OF WASHINGTON.

WRENCH.

To all whom it may concern:

Be it known that I, HnNnv H. WARNER, a citizen of the United States,residing at Tacoma, in the county of Pierce and State of lVashington,have invented certain new and useful Improvements in \Vrenches; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

Ally invention relates to improvements in wrenches, and is designedparticularly for the purpose of combining a rapidly adjusting screw viseWrench and a pipe wrench attachment into a single, easily manipulateddevice.

The object of my invention is to provide a rack jaw attachment forhandling pipe, such that it may be withdrawn from operative position,and protected when it is desired to use the wrench on ordinary work, andmay be quickly and easily adjusted to operative position.

An additional object is to provide a pipe attachment, having bothlongitudinal and lateral movement, in its bearings, so as to preventjamming of the parts, and permit quick release of the pipe attachment,upon reverse movement thereof.

Various forms of attachments have been devised, which have to be securedto the wrench when it is to be used. as a pipe wrench, and removedtherefrom under other conditions, but these require time to adjust, andare frequently ineffective in operation. It is a purpose of my presentimprovement to provide a device of this character which is alwaysavailable instantly, and can be used efficiently without loss of time.

A further object of the invention is to arrange the pipe attachment insuch a manner relative to the remaining parts of the wrench, that themetal is so distributed as to strengthen the weaker parts, and result ina better proportioned and stronger tool than at present on the market.

-With these several objects and advantages in view, my inventionincludes the novel construction and combination of parts hereinafter setforth in detail, and pointed out more particularly in the appendedclaims.

In the accompanying drawing, forming a part of this specification, andwhich is to be read in conjunction therewith, the same in- Spccificationof Letters Patent.

Application filed November 'jatented Mar. 1, 1910.

1909. Serial No. 528,076.

eluding a preferred embodiment of my invention which may be equally welldeveloped in other forms of construction, Figure l: is a view in sideelevation of a wrench provided with my improvements, and showing thepipe attachment in operative position; Fig. II is a partial longitudinalsection, showing the pipe attachment in released position; and Fig. Illa transverse section on the line mm of Fig. II.

Referring more particularly to the draw ings, in which like referencecharacters refer to corresponding parts in the several views, Adesignates the stem, provided with a handle A A is the stationary jaw,mounted on the stem A.

A designates the movable jaw, arranged for adjustment upon the stem AThe movable jaw A" is provided with collars A and A, which surround andengage the stem A and permit. swinging movement relative thereto.Journaled in a cut-away portion of the jaw A", and at the re: r thereof,is a screw-threaded operating-nut A cooperating with threads on the stemA The collar A serves to inclose substantially the nut A and protect thethread thereon against damage or destruction. Arranged at regularintervals around the nut A and diagonally thereon, are openings a, inwhich a punch or nail may be inserted to hold the nut tightly againstmovement, when it is desired to use the wrench as a screw vise.

Formed centrally, on the top of the stem A and adjacent the jaw A, is areinforcing block 13, which abuts the face of jaw A and braces it so asto withstand greater strain, and thus add materially to the life of thewrench. The collar A is cut away at B to engage the sides of the block13 A leafspring B is provided, with a cut-away portion engaging inrecesses formed in the collar A The other end of the spring B is held inthe notch B in collar A. The spring is seated on the upper face of thestem A and acts normally to raise the jaw A, and hold the nut inengagement with the stem.

Loosely mounted in an opening in the forward part of the jaw A, andconfined within the outer surface thereof, is a sleeve C, which isscrew-threaded interiorly, its outer surface being milled, and providedwith a series of openings 0. The opening in which i the sleeve 0 ispositioned, is of suflicient width to allow a slight space on eitherside of the sleeve, and thereby permit lateral movement of the same,upon engaging and releasing movements of the pipe attachment.

C is a rack jaw, which is carried by the screw threaded stem C adaptedto engage the threaded sleeve C, and be operated thereby. The jaw A isprovided with an opening to accommodate the end of the threaded stem Csaid opening being somewhat larger than the stem, to permit a slightlateral play of the same, together with the operating sleeve C, therebypermitting the rack jaw to swing into engagement with the shank A whenpower "is applied to turn the object engaged thereby.

Under ordinary conditions, when the wrench is employed for turning nuts,or as a screw vise wrench, the rack jaw is with drawn into the jaw A andis completely protected, and furthermore is in such a position as not tohinder the proper manipulation of the wrench. When it is desired toapply the wrench to a pipe or circular object, the sleeve C is rotated,quickly moving the stem 0 and the rack C longitudinally of the jaw A,and exposing the rack C to contact with the work.

The several parts are so constructed and arranged, that the entire pipeattachment is normally confined within the surface of the movable jaw,and the only part to be exposed, is the rack jaw, which is projectedfrom its receiving opening for operation.

WV hat I desire to secure by Letters-Patent, and claim, is:

l. A wrench having a shank carrying a stationary jaw, a jaw movable onthe shank, a gripping member and supporting stem normally incased withinthe movable jaw and having both vibratory and longitudinal movementtherein, whereby the gripping member may rest upon the shank whileengaging an object grasped and be freely released therefrom on reversemovement of the wrench.

2. A wrench having a shank carrying a stationary jaw, a movable jawyieldable laterally on said shank, and a gripping member fixed upon athreaded stem, said latter parts being normally incased in and havingboth longitudinal and vibratory movement in the movable jaw.

3. A wrench having a shank carrying a stationary aw, a movable jawyieldable laterally on said shank, and a gripping member fixed upon athreaded stem, said latter parts being normally incased in and havingboth longitudinal and vibratory movement in the movable jaw, and athreaded sleeve to operate the same.

a. A wrench having a shank carrying a stationary jaw, a jaw movable onthe shank, a gripping member and its support normally incased within thelatter jaw, said gripping member having both longitudinal and vibratorymovement with respect thereto, as set forth.

In testimony whereof, I afiix my signature, in the presence of twosubscribing witnesses.
